Juan's cat weighed 3.2 pounds last year. The cat grew and now weighs 7.1 pounds. Solve the equation 3.2 + w = 7.1 to find out how much weight Juan's cat gained.

W is 3.9. The cat gained 3.9 pounds since lat year.

3.9 pounds because you have to subtract them

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?

The answer is 9.7 cm
